COMBINED BELT-SHIFTER AND BRAKE.

SPECIFICATION forming part of Letters Patent No. 369,228, dated August 30, 1887.

Application filed June 25, 1887.

To all whom it may concern.-

Be it known that I, JEREMIAH CASEY, acitzen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Combined Belt-Shifter and Brake; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. p

Figure l of the drawings is an end view of my improved beltAshifter and brake. Fig. 2 Fig. 3 is a sideview of same. Fig. 4 is a modified view of my improved belt-shifter and brake.

The invention relates to improvements in belt-shifting mechanism; and it consists in the construction and novel combination of parts, as hereinafter set forth.

Referring to the drawings by letter, A designates a shaft having upon it the y-wheel B, the iiXed pulley C, and the loose pulley D, a littleless in diameter,preferably, than the fixed pulley, so that the belt b will not wear by friction on it when thrown thereon.

Il is a frame, the standards e e of which rise on each side of the shaft A, andF is ahorizontal rock-shaft having its ends journaled in said standards and an arm, )istandinglaterally from it and secured thereon by aset-screw, as shown.

G is a vertical frame provided with two side strips, g g', which ride on a vertical standard, H, the base-plate of which is secured to the floor by bolts or other suitable means. The end of the arm f is pivoted to the upper end of a link-bar, h, havingits lower end pivoted to the outstanding foot of the adjacent strip g. The opposite strip, g', has its foot loosely connected to the end of the inner arm of the treadle I, pivoted at t' on the base-plate of the stand- Serial No. 2412.510. (No model.)

and made concave o n its face to bear against the rim ofthe fly-wheel B.

When the treadle is operated, the frame Gis raised and the vshoe brought to bear on the iiywheel at the same time that the belt-shifting arms, hereinafter described, move from the fixed to the loose pulley, so as to quickly stop the motion of the shaft.

j is a concavefaccd brakeshoe above the flywheel, and secured at its lower and outer end to the upper end of a bar, K, the lower end of which is firmly fixed to a rock-shaft, 7c, journaled in a part of the main frame of the machine. rIhe upper and inner end of the brake-shoe j is connected by a rope or chain, L, to the outer arm of the treadle, so that when the latter is depressed the brake-shoe will be drawn against the rim of the fly-wheel simultaneously with the shoe J and aid in stopping the rotation of the shaft A.

M and N are the belt-shifter rods, secured at their lower ends upon the shaft F near the journals of the same, respectively. The upper ends of the rods are bent horizontally inward and provided, respectively, with the forks m and n, the arms of which stand on each side of the belt.

O O are horizontal limiting bars, which stand inward in pairs from the standards e e on each side of the rods M and N, to restrict the lateral motion of said bars.

When the treadle is depressed, the shaft F is rocked by means of the arm f and frame G in such manner as to throw the belt from the fixed or operating pulley upon the loose pulley, the shoes then bearing on the fly-wheel to stop quickly the rotation of the shaft. The fork m of the shifter-rod M is below the centers ofthe pulleys to act on a belt ascending to the pulleys, should such a belt be used, so as to more readily shift it. The fork n of the rod Nv is above said centers to more directly act on a belt descending to the pulleys, when such is used.

P is a leverfhandle secured to the outwardlyextended end of the shaft F for the purpose of returning the `belt from the loose to the fixed pulley and for releasing the lower brake-shoe, J, from the iywheel when again starting the machine.

Fig. 4. shows a modification in which two opposite treadles, I, are used, each similarly connected to the foot of the corresponding strip, g. Two similar upper brake-shoes are also used,secured identically, and, as described, to the corresponding treadles situated at points equidistant on each side from the vertical diameter of the iiy-wheel, and connected with Similar rock-shafts, k.

Having described my invention, I elain1- l. The combination,with the shaft, the iixed pulley, the loose pulley, and the belt, of the treadle, the vertically reciprocating frame actuated by the inner arm of the treadle, the link-rod secured to said frame, the rock-shaft journaled in the frame E of the belt-shifting mechanism, the arm connecting said shaft and link-rod, the shifting-rods provided with forked upper ends, the arms of which forks stand ou each side of the pulleys, and the lever-handle on the roek-shaft, substantially as specified.

2. Thecombination,with the shaft,ilywheel, fixed and loose pulleys, and belt,of the treadle, the vertically-reciprocating frame, the brake shoe secured to said fram e, the rockshaft journaled in the frame E, the armf, secured to the rock-shaft and connected to the reciprocating frame by a link-rod, the lever-handle on the rock-shaft, and the belt-shifting rods secured at their lower ends to the rock-shaft, substan tially as specified.

3. The combination, with the shaft and iiywheel thereon, of the treadle, the verticallyreciprocating frame, the brake-shoe secured to the upper end of said frame, the rock-shaft, the arm f, secured to said shaft and connected to the reciprocating frame by the link-rod, the lever-handle on the rock-shaft, and the brakeshoe above the iiy-wheei connected by the bar K to the shaft k, journaled in the main frame of the machine and to the outer arm of the treadle by the rope or chain, substantially as specified. v

4. The co1nbination,with the shaft, the iixcd and loose pulleys, and belt, of the rook-Shaft journaled in the frame E, the shifting-rods M and N, provided, respectively,with the forked ends m and n, the former situated below the centers of the pulleys and the latter situated above the same, and mechanism, substantially as described, for actuating the rock-shaft, as specified.

In testimony whereof Iafiix 1n y signature in presence of two witnesses.
